PETROLEUM-MOTOR.

SPECIFICATION forming part of Letters Patent No. 555,373, dated February 25, 1896. Application led July 24, 1895. Serial No. 557,048. (No model.) Y

To all whom, it may concern.:

Be it known that I, FRITZ HENEioD-SCHWEI- ZER, of Hauterive, canton of Neufchtel, Switzerland, have invented certain new and useful Improvements in Petroleum-Motors, of which the following is a specification.

My im proved motor differs essentially from the similar motors constructed up to now by its great simplicity of construction, a combination of valves and regulating devices giving an automatical and very precise regulating and an improved automa-tical inflammation device.

In the accompanying drawings, Figures l and lbs are a plan view of the whole motor with parts in section. Figs. 2 and 2bis are an elevation of the motor with section on the line y of Figs. l and lb, Fig. 3 is an elevation of part of the motor with section on the line @j z of Fig. ibis. Fig. l shows separately the connection oi' the piston and its rod. Fig. 5 shows the piece N, seen from the left side in Fig. 2.

A is the framing of the motor which forms one body with the cylinder B, the anges h and b2 of which are formed so as to act as supports for the outer mantle of sheet-iron C. The latter has a conical part c tted upon the flange and a rim c2 clasped between the ilange b2 and the cover D. The mantle thus formed is provided with an inlet-tube c3 for cold water and with an outlet-tube c4. The cylinder B is moreover provided with a cock b5 for the removal from time to time of any dirty lubricating-oil that may accumulate therein.

The cover D is provided with a central tube D ending in a chamber D2, connected by means of a tube D3 with the box F. of the escapement -valve E. Over the chamber D2 there is provided a chamber F', having an airhole f4 and containing a double valve F. The chamber F is provided with a tube f which is used only when the motor is to work as gasmotorinstead of working as petroleum-motor, and which is shown in the drawings as being stopped.

Over the upper cone of the valve F a side canal f2 is provided for the introduction of the petroleum contained in a tank G, connected with said canal f2 by means of a tube g. At the point where said canal issues into the axial hole of the chamber F the rod of the valve is provided with an adjustable circular groove which is filled with petroleum, and the contents of which represent the quantity of petroleum introduced into the motor for each explosion. Said circular groove is formed by a tube 7l surrounding the rod f of valve F,and leavin g the latter bare on alength which may be regulated at will.

Over the head H of the tube h there is provided on the upper screw-threaded portion of the rod a nut H. In screwing the latter one brings the lower end of the tube h nearer the cylindrical shoulder provided on the top of the valve, and in so doing the said circular groove is reduced. In unscrewing said nut H one enables the spring I to disj oin the lower end of the tube h from the said cylindrical shoulder of the valve, and in so doing one widens the said circular groove.

The metallic spiral spring I tends to keep the valve F closed, and a lever J, acted upon by means of the centrifugal regulator, as will be described below, is provided at its end with a screw j intended to press upon the rod f of the valve F inorder to open the latter.

The lower part of the chamber D2 is provided with an inner projection d2, in which an incandescence tube d3 is screwed, which is intended to start the motor and which is heated by means of any suitable lamp whatever.

In the tube D3 there is provided a rod d4 intended to become incandescent and to be kept incandescent by the explosion gas escaping from the cylinderB through the canal F2 and the valve E.

The piston K is connected by means of two brackets lo and k2 with the lateral studs formed by the T- shaped end of the rod K. The bracket-s k' and k2 are secured to the piston K by means of bolts, which do not run through the bottom of the piston, so that the latter is not traversed by any bolt whatever, which is a great advantage with regard to its tightness. rlhe rod K is connected as usual to a crank-shaft bearing upon brackets A and A2 forming part of the framing A. Said crank-shaft L bears a centrifugal regulator M, the balls fm.' and m2 of which are connected to one another by means of a spring m and act upon the socket' h' by means of their bent levers m3 and m4. The vertical IOO pin p of a crank-lever Pis engaged in the neck m5 of the socket M', said bent lever P turning horizontally on a pivot p' secured to the framing A.

The above-mentioned lever J is vertically pivoted on the support G' of the tank G, and is provided at its front end with a piece N suspended to said lever J and free to play up or down with said end and to oscillate laterally, so as to follow the motions of the cranklever P, in an opening of which the piece N engages its projection n'. (See Fig. 5.)

The crank-shaft L is provided with a pinion Z gearing into a wheel Q secured on an intermediate shaft q located in a bracket forming part of the framing A. Said shaft q bears a disk R provided with a crank-pin fr. The latter is connected by means of an extensible connecting-rod S with the escapement-valve E, and is also provided with a lever T, the free end t of which is engaged between two projections n2 and n3 of the piece N. The projections n2 and n3 are long enough to prevent the portion t of lever T from escaping them, even when the regulator M causes the piece N to oscillate laterally.

As is to be seen in Fig. 5, the lever T is provided with a shoulder t', which will be placed under the lower edge n4 of the piece N when the latter assumes certain positions. The lever T will then lift the piece N and this will cause the lever J to lower the valve F once at every rotation of the disk R, but when the piece N is kept in the position shown in Fig. 5 by means of the regulator M the ascending motions of the lever T will take place without having the shoulder t of said lever T meeting the edge n4 of piece N, and therefore without having the lever J opening the valve F.

The rod of the valve E is composed of a spiral spring S, the spirals of which are usually pressed against one another, and one of their extremities is connected by means of a screw s with a piece s, hinged to the head s3 of the iixed part of the rod of the valve E. The other extremity of the spring S is connected with the rod S' by means of a pin s2, and the rod S' is connected with the crankpin r.

The object of the extensibility of the connecting-rod S' is to prevent the noise usually caused by the working of the escapementvalve. It is evident that owing' to such extensibility the crank-pin fr is enabled to continue its stroke after the escapement-valve is already closed, the spiral spring being then bent by the further motion of the pin 0', and this will cause the said valve to be pressed on its seat and so prevent its vibrations.

The described motor works as follows: The motor being out of gear and the parts in the position indicated in Figs. l and 2 of the drawings, the shoulder t' of the lever T is placed over the edge n4 of the piece N, and both valves are closed. If one rotates the arbor L, for instance by hand, the connecting-rod S will keep the valve E closed by bending the spring S, and the lever T will open the valve F by means of the piece N and of the lever J, and during the sucking action of the piston the air is exhausted through the tube jt, and

. the drop of petroleum contained in the circular groove of the valve F falls into the chamber D2 and becomes gasied, the chamber D2 being heated by means of a suitable lamp.

(Not shown.) During the compressing action of the piston the compressed gas penetrates into the heated pipe cl3, and when the piston reaches the end of its stroke the explosion takes place and acts upon the said piston for producing the working of the motor. backward motion the piston then drives the gas produced by the explosion back into the box E' of the valve E, this valve E having been opened by the connecting-rod S' acting by compression, and consequently like a rigid connecting-rod. Then the va-lve E is closed again by the action of the connecting-rod S', and the same working takes place again.

The rod CZ* becoming red hot after a small number of explosions, it will then supply the pipe cl3, the heating of which may then be interrupted.

The oscillations of the balls m' and m2 of the regulator M will regulate the admission of the petroleum according to the resistance of the motor.

In order to use the motor with lighting-gas, 011e has only to suppress the tank G and the pipe g and to connect the tube f with the gas supply pipe.

Having thus described my invent-ion, I claiml. In a gas or petroleum motor, a cover D provided with a central tube D', a chamber D2 provided with a projection (Z2 with infiammation-pipe d3 and a tube D3 connecting the chamber D2 with the box E' of the escapement-valve E and containing a rod d* disposed so as to be made and kept incandescent by means of the escaping gases.

2. In a gas or petroleum motor, a double valve F the rod f of which is surrounded by a pipe h intended to form around the rod a circular groove and means for adjusting said pipe to vary the width of said groove7 substantially as described.

3. In a gas or petroleum motor, a centrifugal regulator MV in combination with an oscillating lever P and with a double-armed lever J one arm of which is adapted to act upon the double valve F, the other arm bearing a piece N acted upon by means of the oscillating lever P so as to be brought in or out of reach of a lever T provided on the main shaft of the motor.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
